COVERING FOR B OOFlS AND THE LIKE.

Be it known that I,'EMERsoN B. CAMP- BELL, a citizen of'the United States, residing at Bakersfield, in the county of Kern and State of California, .have invented certain new and useful Im rovements in Coverings for Roofs and the Li e, of which the following is aspecification. y

The object of the present invention is to provide a cheap, yet efiective, waterproof covering for roofs, pipes, the" junctures of lean-to buildings, the under sides of bridges,-

wharves, orthe like. I In the accompanying drawing, the figure is a plan view of the invention applied to a roof, successive layers being removed to disclose the structure.

In making my improved roofing I secure by tacks l coarse burlap or jute fabric 2 to the roof-boards:- 3 or to the bridge or other object which-it is desired to cover, just suflicient to hold the burlap in place in the preliminary stage and not permanently. I then coat this with a paint 4, composed of asphaltum and green neutral mineral oils, such as are distilled'from crude oil at a temperature not lower than 600 Fahrenheit, and are therefore comparatively nonvolatile. The proportions of the above ingredients may vary considerably; but an proportion would be eighty per centum of the asphaltum and twenty per centum of the oils. This composition possesses" an adhesive property, and not only fills the meshes of the burlap, but firmly cements it to' the timber. I next lay on another covering 5 of burlap and coat it with paint 6 in like manner as before, and'I then cover it witha thin coat ofsand 7 I then lay' on another coat- 8 of the paint and then acoat 9 of the sand, according to the thickness or quality of the work desired. "3 My invention of improved roofing differs from prior roofings or other water-tight coverings in this respect, that the burlap is cemented directly to the roof or other structure. In prior roofings paper, cloth, and other'material have been covered with waterproof paint; but the means for fastening them downpermanently tothe roofhas'been not the paint itself, but tacks or nails. It 1s to be understood that I only use tacks to hold the burlap in place while cementing it to the roof and the tacks are not rehed upon as a permanent means of attachment. This is accomplished by means of the cementltious Specification of Letters Patent. ,Application'filedmay 18, 1906. Serial No. 317.554.

ture' effect. it, as in 'rior c onstru 'ctions. Where the roofing is nai ed onto the boards, air canenterf between the. boards and the roofing,

chemical more, by reason of wind-pressure through'the knots and cracks in the boards, causing frequent vibration ofthe roofing, which is very destructive to it. All this is avoided by my construction of having the roofing cemented down to theboards, and the a loosely-woven cloth canex and or contract readily without breaklng where it covers the spaces between the-boards. v

The material may. also be used to close wharves or like structures where there is pedestrian traffic below, reventing any falling of dirt. I It is also use 1 in attaching waterconduits and roofs to the sides of buildings, the burlap being arranged to cover the juncture somewhat after thelmanner of'tin coping, and thus displacing said coping, with consequent economy, as well as being more durable, It can'also be used to cover piping, especially when submerged in salt water or derground. The pipe is first wrapped with burlap and-then coated with; the paint until a waterproof covering is formed. I am aware that it has been proposed to seproducing in time a destructive action on the latter.and, furthercracks or openings inoverhead bridges orplaced un--.

The advantage of is that the roofing is not so liable'tocrack, nor can moisburlap being cure a fabric direct to a metallicroof bypaint- 1 ing said roof and allowing it to dry, also painting the under side of. the down, and immediately applying the fabric to the roof, so that the freshly-painted surface adheres thereto. My invention differs from this in that the. fabric is laid inposition upon the roof or other surface first, .before .any paint is applied thereto, and after a conven ient-extent of surface has thus'been coveredthe cementitious paint is applied to the upper side of the fabric. surface requires, however, that the fabric shall be a coarse open-meshed 01 9,80 that the paint applied on the upper. side thereof can pass through the fneshes' of the interstices of the fabric and secure it directly to the roof fabric as it is-laid- This method of covering a,

lol

ient portion thereof, can be first covered with the fabric and'thenthe paint ap lied on the upper surface thereof, all of whi can be accomplished very quickly. Therefore I 'do not claim, broauly, a fabric cement-ed direct to a roof or other surface; but

"hat I claim is 1. A Waterproof covering for roofs or'other structures comprising, as an exclusive base or foundation, a coarse, openmeshed fabric, and a cementitious paint on the upper side and in the meshes of the fabric, cementing the fabric directly to the roof or other structure to be covered, substantially as described.

2; A Waterproof covering for roofs or other structures comprising, as an exclusive base or foundation, a coarse, open-meshed fabric, a

cementitious paint on the upperiside and in the meshes of the fabric, cementing the fabl 5 ric directly to the roof or'other structure to be covered, and a thin coating of sand on said paint, substantially as de'scribed. I
